# Space Age

Given an age in seconds, calculate how old someone would be on:

   - Earth: orbital period 365.25 Earth days, or 31557600 seconds
   - Mercury: orbital period 0.2408467 Earth years
   - Venus: orbital period 0.61519726 Earth years
   - Mars: orbital period 1.8808158 Earth years
   - Jupiter: orbital period 11.862615 Earth years
   - Saturn: orbital period 29.447498 Earth years
   - Uranus: orbital period 84.016846 Earth years
   - Neptune: orbital period 164.79132 Earth years

So if you were told someone were 1,000,000,000 seconds old, you should
be able to say that they're 31.69 Earth-years old.

# Topics

Some Rust topics you may want to read about while solving this problem:

- Traits, both the From trait and implementing your own traits
- Default method implementations for traits


## Rust Installation

Refer to the [exercism help page][help-page] for Rust installation and learning
resources.

## Writing the Code

Execute the tests with:

```bash
$ cargo test
```

All but the first test have been ignored.  After you get the first test to
pass, remove the ignore flag (`#[ignore]`) from the next test and get the tests
to pass again.  The test file is located in the `tests` directory.   You can
also remove the ignore flag from all the tests to get them to run all at once
if you wish.

Make sure to read the [Modules](https://doc.rust-lang.org/book/second-edition/ch07-00-modules.html) chapter if you
haven't already, it will help you with organizing your files.
